fbsql_error - Returns the error message from previous operation

SYNOPSIS
       string fbsql_error ([resource  $link_identifier])

DESCRIPTION
	Returns the error message from previous FrontBase operation.

	Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_error(3) to retrieve the error text. Note that
       this function only returns the error code from the most recently executed fbsql function (not including fbsql_error(3) and fbsql_errno(3)),
       so if you want to use it, make sure you check the value before calling another fbsql function.

PARAMETERS
	      o $
		link_identifier  -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
		function will try to find an open link to the FrontBase server and if no such link is found it	will  try  to  create  one  as	if
		fbsql_connect(3) was called with no arguments.

RETURN VALUES
	Returns the error text from the last fbsql function, or '' (the empty string) if no error occurred.
